Pump

ABSTRACT

A DEEP WELL PUMP OR THE LIKE HAS AN OVERHEAD CRANKSHAFT WHICH DRIVES TWO CONNECTING RODS, THE LATTER IN TURN RECIPROCATING TWO ELONGATED PIPES EXTENDING DOWN INTO THE WELL. A SUPPORT ELEMENT EXTENDS DOWN INTO THE WELL AND CARRIES TWO STATIONARY CYLINDER MEANS ON WHICH THE ELONGATED PIPES RECIPROCATE. VALVE MEANS ON THE ELONGATED PIPES AND CYLINDER MEANS CONTROL THE PUMPING ACTION AS THE ELONGATED PIPES ARE RECIPROCATED BY THE CRANKSHAFT.

A crankshaft is mounted above the support plate and drives two connecting rods. Each connecting rod has a birfurcated lower end portion having arms extending through suitable openings in the support plate. A discharge elbow or the like is fixed to the support plate between the arms of said birfurcated connecting rod. An elongated pipe connected to each set of arms extends down into the well. An elongated support element mounted on the base also extends down into the well. The lower end of the support element mounts a pair of cylinder means which fit into the lower ends of said elongated pipes for reciprocal relative movement as the connecting rods are reciprocated by the crankshaft. Check valves are provided in the elongated pipes and in the cylinder means to open and close by differences in pressure in the elongated pipes and cylinder means so as to effect a pumping action through the cylinder means, elongated pipes and discharge elbows as the crankshaft reciprocates the connecting rods.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a partial plan view of the pump of the present invention with the top of the casing removed.

FIG. 2 is an elevational view of the upper portion of the pump with the outline of the casing shown in section.

FIG. 3 is an elevational view in section of the major operating components of the pump.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings, the numeral indicates a platform at the top of the well. The platform 10 serves as a base for the pump casing indicated by the numeral 12 in FIG. 2. Located above the platform 10 is a support plate 14 which is supported by the sides of the casing 12 as will be apparent in FIG. 2. The plate 14 carries a pair of uprights 16 and 18 which serve to rotatably support the ends of a crankshaft 20 by suitable bearings. The crankshaft 20 is driven by a motor 22 mounted on the plate 14. An endless belt 23 is interposed between a pulley 24 fixed to the crankshaft 20 and a pulley 26 fixed to the motor shaft thereby to provide the necessary drive between the crankshaft 20 and motor 22.

-The crankshaft 20 has two crank arms 28 and 30, each of which drives a connecting rod 32 and 34 respectively. Connecting rod 32 has a lower end which is bifurcated to define two arms 35 and 37. Extending into the space between the two arms 35, 37 is an elongated pipe 36. The pipe 36 is fixed to the connecting rod 32 by suitable means, for example, by the screw members 33, which are threaded to the arms 35, 37. Also included within the bottom bifurcated portion of connecting rod 32 is one leg of a ninety degree elbow 38. As can be seen in FIG. 3, the bottom of the elbow 38 extends partially into the pipe 36 while the upper leg of the elbow, which is perpendicular to the paper as viewed in FIG. 3, extends transversely of the connecting rod 32. A suitable bracket or support 39 may be provided to support the elbow 38. A seal such as a rubber ring 40 is provided to effect a liquid tight seal between the stationary elbow 38 and the pipe 36 which is reciprocated by the connecting rod 32.

The pipe 36 extends down into the well and at its lower end it is provided with a coupling 41 which mounts a valve seat 42 for a ball check valve 44. Connected to the lower end of the coupling 41 is a pipe 46 which in turn, carries a seal means 48 at its lower end. Extending into the pipe 46 is a cylinder means in the form of a pipe 50 which is fixed to plate 52. The plate 52 is fixed to the platform 10 by means of the support element or pipe 54. Thus it will be apparent that the pipe 46 will be reciprocated up and down relative to the fixed pipe 50 and seal 48 will provide a sliding, liquid tight seal between the pipes 46 and 50.

Also, fixed to the plate 52 is another pipe 56 which in turn has fixed thereto a coupling 58 in which a valve seat 60 for a ball check valve 62 is mounted.

It will be seen that the pump parts on the left hand side of FIG. 3 are identical to those on the right hand side. To avoid repetition the right hand side of FIG. 3 will not be described in detail.

In operation, rotation of crankshaft 20 by motor 22 will reciprocate the crank rod 32 up and down. As it moves up, ball 44 will be seated on seat 42 and water in the pipe 36 will be discharged into the discharge means in the form of the stationary elbow 38 and out to a tank or the like (not shown). Ball 62 will be lifted from its seat 60 due to the expanding volume between coupling 41 and 58 and water will be drawn past the open valve 62 into the pipes 56 and 50. As the elongated pipe 36 moves downwardly the ball 44 will be lifted from its seat 42 and the ball '62 will be seated on its seat 6t} so that water in pipes 56, 50 will pass into pipe 36. This condition is shown on the right hand half of FIG. 3. When the pipe 36 moves up once again, the cycle is repeated. 'In FIG. 3, the pump parts on the left are degrees out of phase with the ones on the right so that as the connecting rod 32 on the left is lifted, the connecting rod 34 on the right is lowered. This is the condition in which they are shown in FIG. 3. Thus as one half of the apparatus is drawing in water, the other half is discharging it.

The distance between base 10 and plate 52 may be one hundred feet or so thereby adapting it for use as a well pump. This is achieved by making the pipes 36 and 54 the desired length.

As shown in FIG. 1, the plate 14 is provided with openings 64 through which the birfurcated arms of the connecting rods 32 and 34 pass.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description and it will be apparent that various changes may be made in the form, construct-ion and arrangement of the parts without departing from the spirit and scope of the invention of sacrificing all of its material advantages, the form herein before described being merely a preferred embodiment thereof.
